WHY IS THIS HAPPENING?


"NEW YORK (CBSNewYork) — For the ninth time so far this year and the second time this week, an NYPD officer has died of apparent suicide.

Law enforcement sources tell CBS2 the off-duty officer died of what appeared to be a self-inflicted gunshot wound to the head.

His wife found him inside their home in the Laurelton section of Queens and called 911. He was taken to a local hospital, where he was pronounced dead."
